STM32L476MEY6TR Description
The STM32L476MEY6TR device is an ultra-low-power microcontroller built around the powerful 32-bit RISC Arm? Cortex?-M4 core that can operate at up to 80 MHz. A floating point unit (FPU) single precision is a characteristic of the Cortex-M4 core that supports all Arm? single-precision data-processing instructions and data formats. Additionally, it incorporates a memory protection unit (MPU) that improves program security and the whole range of DSP instructions.
The STM32L476MEY6TR device integrates high-speed memories, including Flash memory up to 1 Mbyte and up to 128 Kbyte of SRAM, a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), a Quad SPI flash memories interface (available on all packages), and a wide variety of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB
The STM32L476MEY6TR device includes a number of readout protection, write protection, proprietary code readout protection, and firewall protection techniques for embedded Flash memory and SRAM.
Two comparators, two operational amplifiers, two DAC channels, an internal voltage reference buffer, a low-power RTC, two general-purpose 32-bit timers, two 16-bit PWM timers for motor control, seven general-purpose 16-bit timers, and two 16-bit low-power timers are among the features available on the devices. Four digital filters for external sigma delta modulators are supported by the devices (DFSDM).
Furthermore, there are up to 24 capacitive sensing channels available. Additionally, the devices include an internal step-up converter and an integrated LCD driver 8x40 or 4x44.
